| # Recorded B300 comparisons | |
| Ratios are paired geometric-mean speedups in the recorded standalone CUDA Graph scope. Prepared launch is used where available; eager timings remain in the raw results. These are not end-to-end serving speedups or proofs of global optimality. | |

| The old QSA implementation is measured with its declared TileLang 0.1.15, rather than the incompatible 0.1.12 experiment. Current SGLang-based solutions use 0.1.12. See [summary.json](summary.json) for ranges, source run identifiers and coverage; [results.jsonl](results.jsonl) retains separate eager and prepared timings. | |
